This article explores the ways that mothers and children from primarily middle-income European American backgrounds reason about events in which biological and nonbiological objects change in size. In Study 1, mother–child conversations were examined to investigate the events mothers described as growth, as well as the ways mothers explained events occurring in different domains. Findings indicate that although mothers primarily discussed events in domain-specific ways, they exhibited some domain blurring in their talk to children. In Study 2, 3-year-old children (M=3 years, 2 months) and 5
This award is for a Science and Technology Center devoted to the emerging area of nanobiotechnology that involves a close synthesis of nano-microfabrication and biological systems. The Nanobiotechnology Center (NBTC) features a highly interdisciplinary, close collaboration between life scientists, physical scientists, and engineers from Cornell University, Princeton University, Oregon Health Sciences University, and Wadsworth Center of the New York State Health Department. The integrating vision of the NBTC is that nanobiotechnology will be the genesis of new insights into the function of biological systems, and lead to the design of new classes of nano- and microfabricated devices and systems. Biological systems present a particular challenge in that the diversity of materials and chemical systems for biological applications far exceeds those for silicon-based technology in the integrated-circuit industry. New fabrication processes appropriate for biological materials will require a substantial expansion in knowledge about the interface between organic and inorganic systems. The ability to structure materials and pattern surface chemistry at small dimensions ranging from the molecular to cellular scale are the fundamental technologies on which the research of the NBTC is based. Nanofabrication can also be used to form new analytical probes for interrogating biological systems with unprecedented spatial resolution and sensitivity. Three unifying technology platforms that foster advances in materials, processes, and tools underlie and support the research programs of the NBTC: Molecules of nanobiotechnology; Novel methods of patterning surfaces for attachment of molecules and cells to substrates; and Sensors and devices for nanobiotechnology. Newly developed fabrication capabilities will also be available through the extensive resources of the Cornell Nanofabrication Facility, a site of the NSF National Nanofabrication Users Network. The NBTC will be an integrated part of the educational missions of the participating institutions. NBTC faculty will develop a new cornerstone graduate course in nanobiotechnology featuring nanofabrication with an emphasis on biological applications. Graduate students who enter the NBTC from a background in engineering or biology will cross-train in the other field by engaging in a significant level of complementary course work. Participation in the NBTC will prepare them with the disciplinary depth and cross-disciplinary understanding to become next generation leaders in this emerging field. An undergraduate research experience program with a strong mentoring structure will be established, with emphasis on recruiting women and underrepresented minorities into the program. Educational outreach activities are planned to stimulate the interest of students of all ages. One such activity partnered with the Science center in Ithaca is a traveling exhibition for museum showings on the subject of nano scale size. National and federal laboratories and industrial and other partners will participate in various aspects of the NBTC such as by hosting interns, attendance at symposia and scientist exchanges. Partnering with the industrial affiliates will be emphasized to enhance knowledge transfer and student and postdoctoral training. This specific STC award is managed by the Directorate for Engineering in coordination with the Directorates for Biological Sciences, Mathematical and Physical Sciences, and Education and Human Resources.

This model science teacher retention and mentoring project will involve more than 300 elementary teachers in "Lesson Study" of inquiry science around school gardens. Drawing on the rich resources of the University of California Botanical Garden and the science educators at the Lawrence Hall of Science this project will develop Teacher Leaders and provide science content professional development to colleagues in four urban school districts. Using the rich and authentic contexts of gardens to engage students and teachers in scientific inquiry opens the opportunity to invite parents to become actively involved with their children in the learning process. As teachers improve their classroom practices of teaching science through inquiry with the help of school-based mentoring they are able to connect the teaching of science to mathematics and literacy and will be able to apply the lesson study approach in their teaching of other innovative projects. Teacher leaders and mentors will have on-going learning opportunities as well as engage participating teachers in lesson study and reflection aimed toward improving science content understanding and the quality of science learning in summer garden learning experiences and having context rich science inquiry experiences throughout the school year.
The "Salmon Research Team: A Native American Technology, Research and Science Career Exposure Program" is a three-year, youth-based ITEST project submitted by the Oregon Museum of Science and Industry. The project seeks to provide advanced information technology and natural science career exposure and training to 180 middle level and high school students. Mostly first-generation college-bound students, the target audience represents the Native American community and those with Native American affiliations in reservation, rural and urban areas. Students will investigate computer modeling of complex ecological, hydrological and geological problems associated with salmon recovery efforts. Field experiences will be provided in three states: Oregon, Washington and northern California. The participation of elders and tribal researchers will serve as a bridge between advanced scientific technology and traditional ecological knowledge to explore sustainable land management strategies. Students will work closely with Native American and other scientists and resource managers throughout the Northwest who use advanced technologies in salmon recovery efforts. Student participation in IT-dependent science enrichment and research activities involving natural science fields of investigation will occur year round. Middle school students are expected to receive at least 330 contact hours including a one-week summer research experience, a one-week spring break program, and seven weekends of residential programs during the school year. The high school component consists of 460 contact hours reflecting one additional week for the summer research experience. In addition to watershed and salmon recovery related research, students will be involved in other ancillary research projects. A vast array of partners are positioned to support the field research experience including, for example, the U.S. Department of the Interior, Redwood National State Park, College of Natural Resources and Sciences at Humboldt State University, Confederated Tribes of the Warm Springs, University of Oregon Institute of Marine Biology, University of Washington Columbia Basin Research project, the Northwest Center for Sustainable Resources at Chemeketa Community College and the Integrated Natural Resource Technology program at Mt. Hood Community College. The project is intended to serve as a model for IT-based youth science programs that address national and state education standards and are relevant to the cultural experience of Native American students. Two mentors will provide continued support to students: an academic mentor at the student's schools and a professional mentor from a local university or natural resource agency. Incentives will be provided for student participation including stipends and internships. Career exposure and work-related skills are integrated throughout the project activities and every program component. Creative strategies are used to encourage family involvement including, for example, salmon bakes and museum discounts.

Two 8 to 10 week modules, one focusing on cells and the other on reproduction and heredity, serve as the basis for the development of a comprehensive, assessment-driven, middle school science curriculum called "Science for Today and Tomorrow." A curriculum frramework is developed for Life and Physical Sciences to be taught in Grades 6 and 7 and Earth Science in Grade 8. The research-based materials assist students to develop a working knowledge of a core set of ideas that are fundamental to the discipline and ultimately to see how the concepts span the disciplines. The student materials and the teachers' guides are enhanced with classroom-tested assessments and web-based content resources, simulations and tools for gathering and interpreting data. On-line professional development materials allow teachers to gain content knowledge and pedagogical skills. The website also contains an area that provides information for administrators including strategies for supporting teachers and another area for community members to involve them in the students' science learning. The project builds upon the lessons learned in previous materials development projects at TERC.
This sixth through eighth grade comprehensive, project-based, science curriculum focuses on students acquiring deep understandings of the concepts, principles and habits of mind articulated in national science standards. The curriculum builds upon the experiences of the Center for Learning Technologies in Urban Schools developing the LeTUS modules for Chicago and Detroit Public Schools. The project brings together scientists and science educators from three universities, teachers and administrators from six school districts, curriculum speialists from Project 2061, educational researchers from EDC, and Kendall/Hunt publishers. The design principles, arising from research on teaching and learning, include alignment with standards, assessments, contextualization, sustained student inquiry, embedded learning technologies, collaboration, and scaffolds between and within modules. Phase 1 focuses on the development of two units: Structure of Matter and Diversity of Life and Evolution. Learning outcomes are identified, target understanding performances are specified and assessments are designed before the activities are developed. Everday authentic questions that students hold as important provide the basis for projects, contextualize the activities and give coherence to the curriculum. In addition to the student materials and teacher guides, the project develops materials to provide information to administrators and the community to understand and support the implementation of the modules. Issues of language, literacy, culture and diversity are addressed. Professional development materials address teacher attitudes and beliefs while educating the teachers about the new context and pedagogy.
The World Media Foundation is producing and distributing "Emerging Science of Environmental Change." This radio-based project presents new and cutting edge research to the public through National Public Radio broadcasts, Internet radio broadcasts, multi-media web presentations, Internet-based discussion, formal school curricula and public lectures. The goal of the project is to provide the public with a longitudinal view of how those engaged in cutting-edge science formulate theories, structure their inquiries and monitor the ongoing processes, pitfalls, unexpected results and successes of their research. The production team will closely follow the work and processes of one or more research teams over major portions of the 36-month project in order to provide an in-depth understanding of the research process. The project will deliver nine one-hour radio specials and nine additional hours of shorter program segments that will be included in the NPR "Living on Earth" series. The online component of the project will present expanded versions of the audio through its daily web radio service, as well as multi-media web pages with references and discussions linked to the core subjects of the specials. School outreach will be directed primarily at largely urban, under-served middle and high schools. It will use the audio and multi-media web presentations of current research as frames of reference for student instruction in environmental science.
The Informal Science Education Program has been supporting the radio series "Living on Earth" for several years. The World Media Foundation is now adding environmental science and technology features to "Living on Earth" and is developing and testing an outreach component that will involve youth as researchers and radio producers. The science and technology features, ranging in length from four to twenty-four minutes, will depart from the usual news-driven reports on the programs. Many of the segments will illustrate basic building blocks of environmental science, technology and related mathematics. Others will profile diverse pioneers in these disciplines. The radio programs will be the framework for an interdisciplinary exploration program for youth. Working with a team of educators from the Antioch University Graduate Program in Environmental Education, the project staff will develop a program in which secondary school aged youth cooperate with peers to produce professional, concise reporting on local environmental issues. Living on Earth will feature the best of the student work on National Public Radio and highlight these pieces as an expanded feature on its website.
Rutgers University is developing a large-format, scientific, documentary film about the evolving scientific investigation of deep-sea hydrothermal vents. Volcanoes of the Abyss (working title) will be produced in conjunction with Volcanic Ocean Films and produced/directed by Stephen Low. It will examine the communities these vents support and their relationship to the surrounding environment. It also will consider the implications vent discoveries have for our understanding of the evolution of life and our search for life elsewhere in the Cosmos. Much of the filming will be done from on board the Alvin deep ocean research vessel. The companion Educational Outreach Program will reach students in middle and secondary schools and at the college level. Print-based and web-based material also will be designed for use by families. The film and the outreach materials together will be the basis of a substantive educational effort to inform the public about the intricacies and significance of the fascinating, but largely unknown, ecosystem.
